在SmI~3促进下,芳胺与α,β-不饱和腈(酯)在室温下进行共轭加成反应,分别得到相应的β-氨基腈和β-氨基酯,该反应条件温和、中性,收率良好,提供了合成β-氨基腈和β-氨基酯的一种简便方法,并对反应机理进行了探讨。

Promoted by samarium triiodide, the conjugate addition reaction of aromatic amines with α,β-unsaturated nitriles or esters takesplace easily under mild and neutral condition and yield the corresponding β -amino nitriles and β-amino esters respectively in satisfactory yields. The mechanism of the reaction is also discussed.
